BOAT-PUM P.

SPECIFICATION forming part of Letters Patent No. 645,225, dated March 13, 1900.

Application filed February a, 1899. Serial No. 704,446. (No model.)

To all whom it may concern.-

Be it known that I, MATHEW hIARION CU L- LEN, a citizen of the United States, residing at New Cumberland, WVest Virginia, have invented certain new and useful Improvements in Boat-Pumps, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to certain new and useful improvements in boat-pumps.

My invention is particularly adapted for use in connection with inland or ocean vessels and can be used as a hand or power pump for forcing water through openings arranged in the bottom or side of a vessel below the water-line. I

My invention further consists in the novel combination and arrangement of parts hereinafter more specifically described, and particularly pointed out in the claim hereunto appended.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, wherein like numerals of reference indicate corresponding parts throughout the several views thereof, and in which- Figure 1 is a vertical sectional view of my improved pump arranged between the deck and bottom of a vessel. Fig. 2 is a longitudinalsectional view thereof, taken on the line w m, Fig. 1. Fig. 3 is a perspective view of the lower portion of my improved pump, showing the inlet and outlet valves. Fig. 4 is an inverted perspective view of the same. Fig. 5 is aperspective view of the outlet-valve with the spring removed.

Referring to the drawings by rererence-numetals, 2 indicates the bottom of a vessel, which is provided with a series of openings 3, covered on one side thereof by the metallic perforated screen 4:-

Secured to the bottom 2 by means of the screw-threaded bolts 5, which are provided with heads 6, is the cylindrical valve-casing 7, the casing 7 having an opening arranged in the inwardly-extending annular flange 8, formed integral therewith, to allow the heads of the bolts to be countersunk therein. The flange 8 is provided with an upwardly-extending ridge 9 and has suitably connected thereto the transversely-extending guide or support 10, this guide or support 10 being provided with an opening through which the valve-stem 11 of the outlet-valve 12 operates. The outlet-valve 12 is formed of a concentric disk and is adapted to be normally in engagement with the lower face of the flange S and of such a diameter that it will entirely close the opening in the casing 7. The upper end of the valve-stem 11 has secured thereto a stop-pin 13 to arrest the movement of the resistance-spring 14 by means of the disk 15, secured to the upper end thereof, the spring 14. being mounted upon the valve-stem 11 and keeps the valve 12 normally in engagement with the lower face of the flange 8, as above stated.

The valve-casing 7 is provided with a series of radially-extending partitions 16,which have formed integral therewith the collar 17. This collar 17 surrounds the valve-casing 7, but is of less height. The space between the collar 17 and easing 6 forms the inlet-chamber 18. The top of the collar 17 is on the same line as the top of the valve-casing, and the same, as well as the valve-casing, is adapted to support, as well as forming a seat for, the flat concentric ring 19, which is mounted in such a manner as to close the top of the inletchamber 18, this concentric ring forming the inlet-valve and being provided with the setscrews 20, upon'which the valve is elevated. The set-screws act as a guide for theinletvalve, as well as securing the same in position, the lower end of the set-screw 20 being secured in the partitions, as shown in dotted lines. The head of the screw 20 acts as astop for theinlet-valve. (See dotted lines, Fig. 1.)

21 indicates a downwardly-extending cap which surrounds the collar 17, as well as the valve-casing 7, and is provided with the inwardly-extending flange 22 and having the upwardly-extending exteriorly-screw-threaded collar 23 formed integral therewith. The cap 21 is supported upon the collar 17 by means of the shoulder 24, which is formed on the inner face thereof. The cap is also supported, if desired, by means of the set-screws. Secured at its lower end to the upwardly-extending collar 23 is the elongated cylindrical casing 25, in which operates the spring-packed piston 26. This casing I term a piston-chamber. The piston 26 is mounted in the casing and is secured in any desirable manner to the piston-rod 27, which extends above the top of the casing 25 and is connected to asuitable operating-handle 29, as at 30.

31 indicates a chain or cable which is connected at one end to the piston 26, as at 32, and operates over the pulley-Wheel 33 and has its opposite end secured to the counterbalanceweight 36, this assisting the upward movement of the piston, but retarding the downward movement thereof. The pulley-wheel 83 is supported and secured to the top of the casing 25 iii any desirable manner. v The operation of my improved pump is as follows: Assuming that the piston is in position as shown in full lines, Fig. 1, the same being elevated to the position shown in dotted lines in the same figure will elevate the inlet-valve and cause the water to be drawn up ward into the chamber 37 and into the pistonchamber. When the piston is lowered, the pressure of the water will raise the outletvalve from its seat and the Water will be discharged through the outlet-openin gs 3 and through the perforated screen.

It will be noted that various changes may be made in the details of construction without departing from the general spirit of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- In a boat-pump, the combination of a hollow cylindrical valve-casing, an inwardly-extending flange formed integral with the top thereof, a transversely-extending guide secured at each end to the said flange, a disk valve for closing said casing adapted to be normally in engagement with the underneath face of the said flange, a valve-stem operating through the said guide formed integral with the said valve, a coil-spring mounted upon the said stem and adapted to engage the said guide, a series of radially-extending partitions formed integral with the periphery of the valve-casing, a collar connected to the said partitions and surrounding a portion of the said casing forming an inlet-chamber, a concentric ring mounted on the top of the said inlet-chamber for closing the same and forming an inlet-valve, an upwardly-extending guide for the said inlet-valve secured to a pair of the said partitions, a cap supported by the said guides and adapted to surround the said collar, an upwardly-extending flange formed integral with the said cap, a piston-chamber secured to the said flange, a piston operating therein, and means connected to the said pis ton for operating the same thereby operating the said valves alternately, substantially as described;
